I have a cell array 20000 rows and 20 columns with logical values:
A={0 0 0 0 1 0...
0 0 1 0 0 0
1 0 0 0 0 0
0 1 0 0 0 0 ...}
And I would like to convert this array into numeric values of 1 and 0. Can someone help me? Thank you.

This works:
B = double(cell2mat(A));
The cell2mat call converts it from a cell to a logical array, and double converts it to a double array.

double(A) works

I wrote small code
for a=1:number of rows
for b=1:number of columns
if A(a,b)==true
new_matrix(a,b)=1;
else
new_matrix(a,b)=0;
end
end
end

This doesn't work either. Have you tried it?
??? Undefined function or method 'eq' for input arguments of type 'cell'.

for a=1:number of rows
for b=1:number of columns
if A{a,b}
new_matrix(a,b)=1;
else
new_matrix(a,b)=0;
end
end
end
That should work but it is maybe too complicated for you need.

Try this:
B = cell2mat(A).*1;

you're right, my fault. you need to convert from cell first. try:
B = cell2mat(A).*1;
